Toeil whom may come@ f Be kiaowe. thai L Josemi S.v MssNooii', a citizen 'ofthe United States, and a residuem'-l of "the boiough of eooiiyn, in the city of My in" sesion feiates 'io improvements in 1 window reguiezors or window operating devices end an object thereof is the/provision of means for opening end dosing windows lwbieii wiii be' simple in construction and easy izo iisiai. l

Anotiiei" objeee of my invention is to pri vide a window operating devies which may lbe eadiiy iocaied centrally reiative io a window to be operated thereby' and one wherein a window may readily be repiaeed without tbe necessity of disassembiing or taking down ehe entire apparaus.

Another object of this invention is ehe pov'isioe oi? a deviee of the character desig- 'iiaed wherein ,means have been provided whereby the window operated by my de-l vice wii always be maintained in properposii-ion nto enabi'e 'ihe same 'o be moved readiiy 'xrough les guides ai; all times.

@their objeois wiii appear 'from the de f isiied description which foiiows.

Figare 1 shows in elevation my device instaiied in piace at a window;

Fig. 2 is a View o my improved appara- #sus 'teken from iiie Tear' thereof; ,i J

Fig. 3 .is seeion en the iine ie-3 oig. 2 ieoieo' in #she direoiion of leine Je mie;

ie taken subsezieiaiiy on he line 41m-i of Fig. 3, in `she direction of faire arrows thereon.

Referring io the drawings in detail l and 2L designaie a supporting*y frame on which my apparatus is mounted, the par@ l being seemed to the part 2 by screws 3 so that ihe supporting frame may readiiy be taken .spare if desired. Carried' on the member 2 oic the supporting frame is a face plate 4, this face plate and a portionbf fche face 2 of the support-ing frame constituting a easing. Mounted in this easing is a stud 5 on which are mounted a cam 6 and a email gear 7. The stud 5 projects io the exterior of Ehe easing as shown in Fig. 3 and adapted to receive an operating handie 8 the same being heid in piace liiereeri by e set-screw 9. The small gear 'E' meshes y with a large gear i0 mounted within the easing on @stud il 'this same stud earryinga cem 12, the cam l2 being provided with spaced projections 13 on the face thereof adapted 'to cooperate with a ing lei formed integral with or rigidiy secured to a slide 15 mountedwihin the easing, this slide being` .mouiied in guides i6 end being provided with a sies 1'? 'liirough which passes the stud 1l aireadylmentioned. The slidel l5 or the lug le thereon. is in constant engagement with a spring 17 mounied withintiie easing this spring being under tension et ail vtimes and acting to force the slide 15 downwardly as viewed in Fig. 4 to maintain the same in engagement with the 'face oi the Cam 6. As 'che handie 8 is rotaed, therefore, it wiii be seen that the cam 6 wiii be rotated io eens-e the slide 15 to be ieoiprocated,L gbhe up ward inoovermeniJ of this slide, as viewed in Fig. 45 carrying the ing i4 out of engagement with 'the face oiziie cam l2 so ibetehe iatter is 'free to rotate also.

'The' stud l1 edready referred to extends to the exterior of the easing formed by the member 2 and the cover at the upper part `of my apparatus and the side of thesupporiiog frame epposiie to the operating bandire 8 a sprocket 18v is mounted upon the stud, this sproeke'I being .concentric with the large gear 10 already referred to. At

' the lower end of the frame member 1 ande'xtending therei-hro'ugh is a sudi the end of this .sind projecting @heel-gil a sies 20 in the member' l and heid in piace by e nui or other securing means 21. Mounted on the stud 19 is a sprocket 22. This sprocket is rspaced from the face of the frame member l end on the .fece of ibo sprocket adj aeent this frame member is pro1 vided a projection. 23. A ease member 2li is secured by means of serews or other devices 25 to 'the frame member l between the sprocket 22 andtbe' inner face of the supporting frame eed zxoimted whoiiy'wibin' this easing Si provide a coil-spring 26 the inner end of which', designated 27, issecured to a 1ug28 provided for that purpose in die easing whiie the outer end 29 is en" gagged by but iemovabiy secured to the 111g 23 on tile inner fao-e of "che sprocket 22.

From ibis it wiii be seen that as the sproekeiI 22 is rotased thev spring' 26 Wiii be wound and unwound depending upon the direeincome to be secured to e Window, said plate being in sections hinged 'together so as to form e slot between them to receive seid pin Whereby the Window may be detached from operetive connection with the chain Without removing the Seid plate from `the Window.

3. A window operating apparatus coinprising i driving member for e, Window, e spring-preesed slide carrying a lug, a cern copereting with seid lug, actuating mechanism for 'the driving member7 and e. cem driven by seid actuating mechanism for reciprocating said slide to move the lug carried thereby into and out of operative .relation with its cooperating cem to lock the seid driving member in predetermined points in the travel of the Window. l

el. In e window., operating appara-tus, the combination of a chain to beopere'tively connected to e Window, e frame, a, pair of sprockets disposed on seid freine for supporting seid chain, n casing on said frame, a gear therein concentric with one of Said sprockets, and rotating therewith, a second gear in said casing' and in mesh with the ,tiret-named gear, an operating handle for driving said second gear, a @am rotatable with said second gear, a slide actuated by seid cam, and an additional cam coperating with seid slide to lock said chain when 'the seid operating handle is actuated,

5. In e Window operating device the combination of e frame, sprockets carried thereby, e driving member adapted to' be attached to a window and mounted upon seid sprockets, Ineens for actuating Seid driving member, a cam rotatably mounted on seid frame fend concentric with one of said sprockets, a gear rigidly secured to said cam, a slideble member carrying e spring-.pressed lug coperating with seid cam, a rotatable cam engaging said slidable member end a, gear secured thereto meshing with the second-named gear whereby rotan tion will be imparted to the first-mentioned cam and longitudinal movement will be imparted to the slidable member to cause the lng carried thereby to be moved into and ont of engagement with the irst-mentioned cam to canse the driving member to lbe .locked 1n predetermined positions.
